The traffic of the local TER trains would be severely disrupted, according to the French railway company SNCF, while about a quarter of the fast TGV trains would not run.
International connections have also been affected. According to information from the Belgian NMBS International, some TGV-INOUI trains between Brussels-South and French destinations will not run on Tuesday, Wednesday and Thursday.
The four trade unions at the SNCF want to increase the pressure on wage negotiations with the strike.
